AUTOMATIC STAND-LIFTER FOR MOTOR-CYCLES.

To all whom it may concern:

Be it known that I, Jnssn C. PIERCE, a citizen of the United States,residing at Tacoma, in the county of Pierce and State of IVashington,have invented certain new and useful Improvements in Automatic StandLifters for Motor-Cycles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invent-ion relates to motor cycle stands and is particularlydesigned for the use of stands arranged on the rear portions of motorcycles.

The lifter is designed to be placed upon the market as an article ofmanufacture and can be readily attached to stands of different kinds,although it is to be understood that the lifter may be secured to thestand at the time of manufacture.

The object of this invention is to provide means whereby the stand isautomatically lifted and held in adjusted position.

A further object is to provide a safety de vice by the provision ofspring lever members should the stand become loosened.

\Vith this and further objects in view the invention consists of certainnovel construction and combination of parts which will be hereinaftermore fully described and claimed.

In the accompanying drawings: Figure 1 shows a side elevation of themotor cycle stand equipped with my improvement. Fig. 2 is a back view inelevation with the stand in use. Fig. 3 is a front elevation of a coilspring and lever members. Fig. 4 shows a side elevation of myimprovement. Figs. 5, 6, 7, and 8 show parts of my improvement insection and elevation. Figs. 9 to 12 inclusive show modifications of mydevice in section and elevation.

Similar characters indicate corresponding parts in all of the views.

Referring to the figures by the characters, 21. is a conventional formof stand pivotally mounted to frame 22 by bolts 23, said bolts beingsubstituted for the ordinary rear bolts which hold the stand 2]. atpoint 24 below the axle 25. Bolts 23 also support ferrules 26 andwashers 27 as shown in Fig. 5. Arranged around the ferrules 26 and heldin position by the flared heads 28 and washers 27 are coil springs 2%)With projecting lever Specification of Letters Patent.

armsBO and 31. The arms 30 are secured to stand 21 and arms 31 aresecured to frame 22 by angle ends 32 formed on the ends of the arms 30and 31.

Fig. 12 represents a modification of bolts 23 used in connection withthe enlarged opening 38, formed in the flange 28 on ferrule 26 andwasher 27. In this construction a shoulder 23% extends out to the threaded portion of the bolt, thus affording a portion of the bolt as washersurface against the frame 22.

The operation of my improvement is as follows: To bring the stand 21 inuse it is detached from catch arranged on mud guard 36 and presseddownwardly, and at the same time the machine is pulled backward until itrests upon the stand by its own weight, as shown in Fig. 2 and dottedlines 21 in Fig. 1. To release the stand 21 the machine is moved forwarduntil the stand is free of the ground. Immediately the springs 29 givean upward pull to the stand, snapping it into catch through the mediumof lever arms 30 and 31. The spring 29 holding arms 30 and 31 in thisposition provides a safety means should catch 35 fail to hold the stand21.

It is obvious from the foregoing that my device affords an improvementin motor cycle stands that is quickly and easily operated, and providesin combination a simple means for safety.

To keep the rear wheel of the motor cycle in its elevated position, abracket 37 is secured at one end to the stand 21, and near its other endto a bracing rod 38, which is also fastened to the stand 21. Thisbracket 37, being rigidly secured to the lifter, will engage the frameof the motor cycle at 39 and prevent any further rearward move ment ofthe machine as it. is being raised to its elevated position.

I claim:

The combination with a cycle frame having a bearing for an axle, of abolt secured to the frame below the axle, said bolt having an enlargedshank with a shoulder at the end of the shank and spaced from thethreaded end of the bolt, a washer carried by the bolt between theshoulder and the frame, a sleeve having an outer flanged end carried bythe shank, a coil spring surrounding the sleeve the ends of the springprojecting from the coiled portion, a supporting at times the free endof the supporting 10 member.

In testimony whereof Iatfix my signature in presence of two Witnesses.
